Efficacy and Safety of Org 25969 Administered After Zemuron® (MK-8616-042)
August 30, 2018 updated by: Merck Sharp & Dohme LLC
A Multi-center, Randomized, Assessor-blinded, Phase II, Parallel Dose-finding Trial in Subjects of ASA Class 1 - 3 to Assess the Efficacy and Safety of 5 Doses of Org 25969 When Administered at 1-2 PTCs After Administration of Zemuron®
The primary objective of this study is to explore the dose-response relation of MK-8616 (Org 25969) given as a reversal agent of Zemuron® at 1 to 2 post tetanic counts (PTCs); both Zemuron® and MK-8616 are administered by intravenous (iv) infusion.
Another goal of the study is to evaluate the safety of single doses of MK-8616 administered to participants of American Society of Anesthesiologists (ASA) Physical Status Class 1 (otherwise normal, healthy participant); Class 2 (participant with a mild systemic disease); or Class 3 (participant with a severe systemic disease that limits activity, but is not incapacitating).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time From Start of Administration of MK-8616 to Recovery T4/T1 Ratio to 0.9
Time Frame: Up to 90 minutes
|
The mean time from the start of MK-8616 administration to recovery T4/T1 ratio of 0.9 was determined.
Less time indicates faster recovery from NMB.
The ratio of T4 (fourth twitch; amplitude of fourth response to train of four [TOF] stimulation is expressed as percent of control T4) over T1 (first twitch; amplitude of first response to TOF stimulation is expressed as percent of control T1) ranges from 0 (complete loss of T4 twitch response) to 1.0 (complete recovery of T4 twitch response).
For TOF stimulation, 4 consecutive square wave supra-maximal stimuli of 0.2 msec duration were delivered at 2 Hz every 15 seconds.
Neuromuscular monitoring was performed with the TOF-Watch® SX.

Up to 90 minutes

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants Experiencing ≥1 Adverse Events (AEs)
Time Frame: Up to 7 days following MK-8616 administration
|
The percentage of participants experiencing ≥1 AEs was determined.
An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have to have a causal relationship with this treatment.
|
Up to 7 days following MK-8616 administration
